Details
Since the rolling elements in cylindrical roller bearings make line contact with raceways,these bearings
can accommodate heavy radial loads . The rollers are guided by ribs on either the inner or outer ring ,
therefore these bearings are also suitable for high speed applications.Furthermore, cylindrical roller
bearings are separable ,and relatively easy to install and disassemble even when interference fits are
required. Double and multiple row bearing arrangements are also available. Single row cylindrical roller
bearings can accommodate heavy radial loads and high speeds. They are manufactured in several
different designs,the main difference being in the configuration of the flanges .The most popular are
the NU,N,NJ and NUP designs.
